'  Examine the structure in text format:
Dim txtStruct As String = mime.GetStructure("text")
Log(txtStruct)

'  The MIME structure as indented text is:
'  multipart/alternative
'      text/plain
'      multipart/related
'          text/html
'          image/jpeg
'  

'  Now examine the structure in XML format:
Dim xmlStruct As String = mime.GetStructure("xml")
Log(xmlStruct)

'  The MIME structure as XML is:
'  <multipart-alternative>
'      <text-plain />
'      <multipart-related>
'          <text-html />
'          <image-jpeg />
'      </multipart-related>
'  </multipart-alternative>
